82 <p>FFTW&rsquo;s &ldquo;advanced&rdquo; interface supplements the basic interface with four
83 new planner routines, providing a new level of flexibility: you can plan
84 a transform of multiple arrays simultaneously, operate on non-contiguous
85 (strided) data, and transform a subset of a larger multi-dimensional
86 array. Other than these additional features, the planner operates in
87 the same fashion as in the basic interface, and the resulting
88 <code>fftw_plan</code> is used in the same way (see <a href="Using-Plans.html#Using-Plans">Using Plans</a>).
